c. duration_in_ms >= 100: Sets the break condition for the specified period of milliseconds (note that this

integer is only accurate to the tenth of a second).

The ifUserData interface provides the following:

• SetUserData(user_data As Object): Sets the user data that will be returned when events are raised.

• GetUserData() As Object: Returns the user data that has previously been set via SetUserData(). It will

return Invalid if no data has been set.

Example: This code waits for a serial event and echoes the input received on the serial port to the shell.

serial = CreateObject("roSerialPort", 0, 9600)

p = CreateObject("roMessagePort")

serial.SetLineEventPort(p)

serial_only:

msg = Wait(0,p) ' Wait forever for a message.

if(type(msg) <> "roStreamLineEvent") goto serial_only 'Accept serial messages only.

serial.SendLine(msg) ' Echo the message back to serial.
